5 Instructions

General Surface Prep

USE CHEMICAL-RESISTANT GLOVES, such as nitrile,

when handling product.

Surfaces must be structurally sound. Remove all grease, oil, dirt,

curing compounds, sealers, adhesives or any other contaminant that

would prevent a good bond. Glossy or painted surfaces must be

sanded, or abraded, and stripped of all contaminants. Concrete must

be cured 28 days and accept water penetration. Concrete must be free

of efflorescence and not subject to hydrostatic pressure. Concrete

slabs should have a coarse finish to enhance the bond. Plywood

flooring including those under resilient flooring must be structurally

soundand meet all ANSI and deflection requirements. For questions

about proper subfloor installation, call Technical Services. Smooth

concrete surfaces, existing glazed tile, terrazzo, or polished stone

should be scarified. Sheet vinyl must be well bonded and stripped of

old finish. Roughen the surface by sanding or abrading, then rinse and

allow to dry. Expansion joints should never be bridged with setting

material. Do not sand flooring materials containing asbestos. Ambient

temperatureshouldbemaintainedabove50°F(10°C)orbelow100°

F(38°C)for72hourstoachieveproperbond.

Bonding to Concrete Surfaces

Concrete or plaster must be fully cured and must accept water

penetration. Test by sprinkling water on various areas of the substrate.

If water penetrates, then a good bond can be achieved; if water

beads, surface contaminants are present, and loss of adhesion may

occur. Contaminants should be mechanically removed before

installation. Concrete must be free of efflorescence and not subject to

hydrostatic pressure. Concrete slabs should have a coarse finish to

enhance the bond. Smooth concrete slabs must be mechanically

abraded to achieve proper bond.

Bonding to Lightweight Cement and Gypsum Surfaces

Lightweight or gypsum based underlayments must obtain a minimum

2000 psi (13.8 MPa) compressive strength. The underlayment must be

sufficientlydryandproperlycuredtothemanufacturer’sspecifications

for permanent, non-moisture permeable coverings. Surfaces to be

tiled must be structurally sound and subject to deflection not to exceed

the current ANSI Standards. Surfaces shall be free of all grease, oil,

dirt, dust, curing compounds, waxes, sealers, efflorescence, or any

other foreign matter.

MegaLite®RSUltimateRapidSettingCrackPreventionLargeFormatTileMortar/TDS120

All Lightweight cement or Gypsum surfaces should be primed. with a

properly applied sealer or a primer coat of RedGard, consisting of 1

part RedGard diluted with 4 parts clean, cool water. Mix in a clean

bucket at low speed to obtain a lump free solution. The primer can be

brushed, rolled or sprayed to achieve an even coat. Apply the primer

coat to the floor at a rate of 300 ft2/gal (7.5 M2/L). Drying time

depends on site conditions, but is normally less than 1 hour. Extremely

porous surfaces may require 2 coats. At this point, RedGard can be

applied to the primed lightweight or gypsum based surface. Refer to

the individual product data sheet or packaging directions for application

instructions. Expansion joints must be installed in accordance with local

building codes and ANSI/TCNA guidelines. Refer to TCNA EJ171.

Bonding to Plywood Surfaces

Plywood floors, including those under resilient flooring, must be

structurally sound and must meet all ANSI A108.01 Part 3.4

requirements. Maximum allowable deflection: L/360 tile L/720 stone.

See TCNA F150-13 tile installations, TCNA F141-13 and F250-13 for

stone. For questions about proper subfloor installation requirements,

callCustom®TechnicalServices.

Bonding to Backerboards

As an alternative to an additional layer of plywood, WonderBoard Lite

backerboard may be installed over plywood subfloors for ceramic tile

installations. Refer to TCNA F144-13 tile installations and TCNA F-250-

13forstone.CallCustom®TechnicalServiceswheninstallingnatural

stone over plywood subfloor.

Bonding to Existing Surfacing Material

Existing Ceramic Tile, Resilient Flooring or Plastic Laminates: Resilient

flooring or plastic laminates must be well bonded, as well as clean and

free of all contaminates. Roughen the surface by sanding or scarifying;

rinse and allow to dry. Do not sand flooring that contains asbestos. For

existing well bonded ceramic tile, mechanically abrade the surface.

Rinse and allow to dry. When sanding, an approved respirator should

be used.

Bonding to Cutback Adhesive

Adhesive layers must be removed, as they reduce mortar bond

strength to cement surfaces. Use extreme caution; adhesives may

contain asbestos fibers. Do not sand or grind adhesive residue, as

harmful dust may result. Never use adhesive removers or solvents, as

they soften the adhesive and may cause it to penetrate into the

concrete. Adhesive residue must be wet-scraped to the finished

surface of the concrete, leaving only the transparent staining from the

glue. To determine desirable results, do a test bond area before

starting. Refer to the RFCI Pamphlet, "Recommended Work Practices

for Removal of Resilient Floor Coverings", for further information.

Movement Joint Placement

Movement joints are required for perimeters and other changes of

plane in all installations. Expansion joints and cold joints, as described

in ANSI A108.01, should never be bridged with setting material. They

must be brought through the tile work and filled with an appropriate

elastomericsealant,suchasCustom's®100%Silicone.Contact

Custom's®TechnicalServicesforthepropertreatmentofcontrolor

saw cut joints. Refer to TCNA EJ171, F125 and F125A.

Mixing Ratios

Mix 5.75 - 6 qts (5.4 - 5.7 L) clean water per 30 lb (13.6 kg) bag of

mortar.

Mixing Procedures

Mix by hand or use a low 150-200 RPM speed 1/2" (13 mm) drill to

achieve a smooth, paste-like consistency. Let the mixture slake or

stand 3 minutes; stir again and use. Stir occasionally, but do not add

more water. When properly mixed, troweled ridges will stand without

slump.

Application of Product

Installation must conform to ANSI A108.5. Use a properly-sized notch

trowel to ensure proper coverage under tiles. Using the flat side of the

trowel, apply a skim coat of mortar to the surface. With the notch side

ofthetrowelheldata45°angle,applyadditionalmortartothe

surface, combing in one direction. Press the tile firmly into place in a

perpendicular motion across ridges, moving back and forth. The

perpendicular motion flattens ridges and closes valleys, allowing

maximum coverage. With some tile, back-buttering is advisable. Adjust

the tile promptly and beat it in with a beating block and rubber mallet.

Periodically pull up a tile and check the back to ensure proper adhesive

coverage. If the material has skinned over (not sticky to the touch),

recomb with the notch trowel; if too dry, remove and replace the dry

material with fresh material. Thin-Set Mortar should not be used to fill

low spots in the flooring. Mortar thickness should be less than 3/4"

when beat in.

Curing of Product

Curing time is affected by ambient and surface temperatures and

humidity. Use the following as a guideline. Allow 3 hours before

grouting, 4 hours before light traffic, and 3 days before heavy or

vehicular traffic. Before exposure to heavy or vehicular traffic, assure

assemblyisrated“HeavyorExtraHeavy”perTCNAService

Requirements. As necessary, use plywood or other load distributing

protection when moving heavy equipment across tiled assembly.

Submerged installations must cure for 14 days before filling with

water.

Cleaning of equipment

Clean with water before the material dries.

Storage

Store in a cool dry area.

Health Precautions

This product contains Portland cement and free silica. Avoid eye

contact or prolonged contact with skin. Wash thoroughly after

handling. If eye contact occurs, flush with water for 15 minutes and

consult a physician. Do not breathe dust; wear a NIOSH approved

respirator.

Conformance to Building Codes

Installation must comply with the requirements of all applicable local,

state and federal code jurisdictions.
